RAILWAYQCAR...

To all whom it may concern: I

Be it known that I,FRANK J. GILROY, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Railway-Cars, of whichthe following is aspecifi cation, reference being had therein to theaccompanying drawing.

The object of thisinvention is to provide cars adapted to serve, withoutchange or addition, for a wide range of uses, and to serve in each casemore satisfactorily than the special car usually employed for thespecific purpose. .The same car answers perfectly for carrying ordinarymerchandise, grain or other loose granular material, or automobile orother goods too large to pass into any ordinary car. The car is providedwith two contiguous, oppositely sliding main doors placed edge to edge,and one of these doors has in its upper part a small doorforloadinggranular material. Both the main'doors are adapted'fo'r continuousmarginal engagement, when closed, with flanges on the car itself. Whenthe car is to be used" like an ordinary box car, the loading door isclosed and internally locked and one of the main doors is so secured asto have all the strength of a part of the car wall, which it virtuallybecomes. When granular material is to form the load, the

, loading door is opened and then both main doors are closed and locked.When the loading is completed, the small door is closed andautomatically lockedon the inside, so that it can not be againopened'until the main doors are opened. When automobiles or similarlylarge pieces of freight are to be carried, both main doors are openedfor loading and then all the doors are closed and securely locked.

In the accompanyin drawings, Figure l is a side elevation of t e centralportion of a car provided with my devices. Fig. 2 is a section ontheline 2-2, Fig. 1. Fig. 3

shows'the outer face of a post at the meeting edgesof the main doors.Fig. 4 shows the fastening for the upper end of the post, looking fromthe interior of the car. Fig. 5 is a horizontal section through the postand the adjacent parts of the main doors. Fig. 6 is a sectional viewshowing the fastenin devices at the lower end of the post. Fig. is asection on the line 7-7, Fig. 1.

walls and B I-beam door posts'of a car having sills D, upper framework Eand floor F. Below the door opening'and extending in each directiontherefrom along the out side of the car is a fixed track G'forined bythe upturned marginalportion of 'a plate Gr bolted to the car. Directlybelow the door opening this plate is widened and its upper marginalportion is bent outwardly and then downwardly to form a hook orcontinuous flange G At each door post an analogous vertical flange onthe post extends from the lower. to the upper side of the opening, andover the upper side of the opening 'is an analogous downwardlyprojecting flangeG. Two doors "H, -H cover the whole opening, thebeveled vertical edge of one overhanging the contiguous oppositelybeveled edge of theother. Both are supported below by rollers I restingupon the track G, and both havebelow upturned marginal flanges J I whichengage the flange G and at their outer lateral margins analogousinwardly turned or hooked flanges J 5 engaging the vertical flangesrespectively, of the door posts when both doors are closed. The uppervmargins of both doors slide beneath the flange G, and the overhangingedge'of one door prevents the independent outward springing 0f- 'floorof the car to a head jamb or lintel above the door opening and slidesbodily with the door to which it is secured. To the lower end of thispost is rigidly fixed a heavy metal member L grooved below in,

or parallel to, the plane of the door toslide-f over a strong metal lugM projecting from a block M sunk in'the floor and loolted'to the carsill. A stop shoulder L limits the sliding in one direction, and asliding bolt L automatically looks it against return movement when thatlimit is reached.

At its upper end the post carries a block N which, like thatat the lowerend, is pref-' erably of malleable iron or steel, adapted to slide asthe door closes, behind-a block 0, securely fixed to the frame ofthe'c'ar, and to belocked against further vzllinytin'g by a pin P;' Fromthe constructionit is plain that the post will resist any ordinaryoutward thrust upon itself or either door and that when the door towhich it is secured is closed, this door offers even greater resistancethan other portions of the car wall. lvioreover, the engagement of thedoor and car flange at the upper, lower and rear or outer edge is suchthat granular material cannot pass, great pressure tending to makeescape more diflicult, if possible. This door being thus closed and thepost locked in place, the other door may be used as if the first doorwere a part of the car wall. Obviously when it is closed its forwardmargin lies beneath or within the overhanging edge 0t its companion andall its other edges are in engagement at all points with flanges fixedto the car. This door is provided with small oppositely sliding loadingdoors CZ having locking devices (.Z not accessible from outside the car.

As has been stated, ordinarily the door secured to the central post iskept closed, but when necessary the post-locking bolts are withdrawn anddoor and post are moved aside together leaving a greatly enlarged dooropening.

It is to be observed that whatever the position of either door or thecentral post, all parts are securely held against moving from theirnormal plane into position for injuring passing cars.

What I claim is:

1. The combination with a car having a continuous, door-overlappingflange extending along the upper side of a wide door opening, continuousexternal flanges extending along all the remaining sides of that openingand turned from said opening, of

two doors arranged to slide oppositely within the flange first mentionedand provided with hooked flanges to engage at every point when the doorsare closed, the lower and lateral flanges around said opening, the edgeof one door being adapted to overlap the meeting edge of the other doorand being made substantially as inflexible as the body of the car wall.

2. The combination with a grain and automobile car having a continuousexternal, door-overlapping flange along the upper side of a wide dooropening, and continuous external flanges turned from said opening andextending along the remaining three sides thereof, of two oppositelysliding doors of thin metal, meeting centrally with respect to saidopening and one passing within an overhanging margin of the other, adisplaceable vertical beam extending from top to bottom of the opening,overlapped by both doors and secured to the door having the overhangingmargin to keep it rigidly rectilinear; both said doors sliding within.the flange first mentioned, provided with deflection-resistingreinforcement along their upper margins and along. their lower andnon-meeting margins with hooked flanges to engage, when the doors areclosed, the corresponding flanges around said opening.

5. The combination with a car having a continuous door-overlapping,external flange along the upper side of a wide door opening, continuousexternal flanges turned from the opening and extending along theremaining sides thereof, and a track below said lower flange of twodoors arranged to slide oppositely within the flange first mentioned andprovided with hooked flanges to engage, at every point when the doorsare closed, the lower and lateral flanges around the door opening, andwith rollers to run upon said track, one door being provided in itsupper part with small internally looking grain doors, and the edge ofone door being adapted to overlap the meeting edge of the other door andmade substantially as inflexible as the body of the car wall.

4. The combination with a car having on all sides of its wide dooropening continuous door-engaging flanges and provided. at the upper andlower sides of said opening with heavy metal stops fixed to the frame ofthe car centrally of the opening, of op positely sliding doors of thinmetal having all their margins stifl ened by inwardly turned hookedflanges and all outer margins held when the doors are closed, at allpoints, by the flanges, respectively, about said opening, and the marginof one door overhang ing the meeting marginof the other door, and aT-beam fixed to said overhanging margin and adapted to slide into andout of engagement with said stops as its door closes and-opens.

In testimony whereof I aflix my signature in presence of two Witnesses.
